To eliminate some odds, try passing the file using a complete path, e.g.

  $ lilymidi --pretty `pwd`/aeiou.mid

Thanks Jan-Peter& David. Yes, what I submitted above was very much a draft,
as I had got as far as I could by myself. I suspected I would learn more
than just how to put it in \global, for example:

> Why define-scheme-function when returning music?

> Perhaps this function had another meaning in the first place?

Yes, that. Plus me being a complete Guile-noob :-)

I’m getting a much better idea of how Lilypond code interacts with Scheme
now. So even though music is a Scheme value, define-music-function is
optimized for returning music and would work better in corner cases?

> But for a more robust implementation, there need to be score-level
context-properties - perhaps an engraver. We'll see later ;)

90% of the music I work with is one staff to a part, eg renaissance choir
music or chamber music, so personally I don’t need much robustness. For
listening to renaissance music I set all voices to clarinet (artificial,
not sampled) with the panning spread. It lets me hear all the parts and
identify which part a problem might be in.

Thanks again,
Vaughan

RE: Rolled Chord

[Mark Stephen Mrotek]

Kieren,

Thank you for your reply.
My limited experience with the computer language for commands suggests two
things.
1. The command requires a " = t."  It should be tieWaitForNote = t.
2. Commands can contain other symbols, "\," " ' (apostrophe), " and " #. "
Should any of these be included.

Mark

 Just a question or two, based on my own experience. Did you first
remove (or purge) LilyPond 2.14.2 before installing 2.18.0? Otherwise,
your system may still be using the older installation. Also, where did
you install the latest version? If I remember correctly, the automatic
installation of 2.14.2 places the bin files in /usr/bin. To keep this
consistent, I installed LilyPond 2.18.0 in /usr/, using the --prefix
argument. Third, have you established that the .el files are exact
copies by using a program like diff? To be utterly safe, I always
remove the old .el files (which even purging will not remove) and
replace them with the .el files found in the new installation. Lastly,
if you use the info files to read the manuals, be sure to move them
from their original location to the /usr/share/info directory;
otherwise, you will not have access to them by the normal means.

Yes, I have now found all seven files elsewhere, and checked that the
six I had already found are identical to the copies I found in the other
directory.  So all now seems to be well.

Some time when I have some time to spare, I must update all this stuff

Hmmm. You should have found seven .el files in the original lisp
directory, one of them being lilypond-words.el. Be sure to move them
all into one of the directories in your loadpath. For example, I am
using ubuntu-13.04, and I have moved all of those files to

I suggest not to rely on the distribution package, especially of a LTS
version.
You can install the generic package. It's very easy, have you tried? Try
and let us know if you have problems.
If you install it with sudo the binary will be in /usr/local/bin which is
in your PATH for sure. If you don't use sudo it will be installed in your
home directory and you'll find it only if ~/bin is in your path, which
might not be your default.

For example, I have:

$ echo $PATH
/home/fede/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

$ which -a lilypond
/home/fede/bin/lilypond
/usr/local/bin/lilypond
/usr/bin/lilypond

$ lilypond -v | grep "GNU LilyPond"
GNU LilyPond 2.19.1
$ /usr/local/bin/lilypond -v | grep "GNU LilyPond"
GNU LilyPond 2.18.0
$ /usr/bin/lilypond -v | grep "GNU LilyPond"
GNU LilyPond 2.16.2

Which means that I chose to put the latest development version (2.19.1) in
the first path, the latest stable (2.18.0) in the second and the old stable
(2.16.2) in the last.

Re: How do I get Emacs mode?

[David Sumbler]

Thanks for the link to your explanation of what to do to get Emacs
Lilypond mode working.

This was easy to follow, and I now have syntax highlighting etc. working
for Lilypond files.

Just one thing, though: when I load a .ly file into Emacs
I get a message:

Warning: `lilypond-words.el' not found in `load-path'. See
`lilypond-init.el'

I've had a look at lilypond-init.el, which is no help.  I also found a 
scripts/build/lilypond-words.py file in the Lilypond 2.18.0 source that
I downloaded, but when I tried to run that in python I got:

Traceback (most recent call last):
  File "Downloads/lilypond-2.18.0/scripts/build/lilypond-words.py", line
21, in 
s = open ('lily/lily-lexer.cc', 'r').read ()
IOError: [Errno 2] No such file or directory: 'lily/lily-lexer.cc'

How do I obtain or generate the lilypond-words.el file?

Incidentally, in response to David Kastrup's suggestion "How about
upgrading Ubuntu?", the reason I am sticking with Ubuntu 12.04 at the
moment is because it is an LTS (long term support) version.  I shall
probably change to 14.04 LTS a few months after it is released (so that
the worst bugs can be sorted out first).

As a professional musician and not a computer expert (as you can tell!),
I find that reinstalling Ubuntu every other year is more than enough
hassle, especially as I have to do it on 2 computers.  A new
installation every 6 months is just asking too much, and in my
experience Ubuntu upgrades (as distinct from clean installs) always
cause immense problems, so I have given up on them.

I don't think that this page encourages to use the default distro version,
but it's true that it doesn't encourage to use the latest stable. I think
that it should, I've added a couple of suggestions in this issue:

Actually, the default is #0. The reason the code did not work is
because, as I stated earlier, the ways of calling overrides has
changed and so will not work unless you have upgraded to the latest
stable version.

I suspect that you had installed 2.14.2 via ubuntu's apt-get
mechanism, which placed all the files in their correct location.
Manual installations, via the .sh script, will not place certain
files, such as the .el or .info files, where you might wish them.

How do I get Emacs mode? (was: Dynamics not correctly aligned)

[David Sumbler]

Thanks to all for your responses to my enquiry about misaligned
dynamics.  Thanks especially to Hwaen Ch'uqi, who tried to answer my
question: unfortunately,
\override Dynamics.DynamicText.self-alignment-X = #-1
(modified for the different syntax in Lilypond 2.14.2) did not solve the
problem.  I think this is because -1 is the default value in any case.

You all suggested, as I was afraid you would, that instead of trying to
get 2.14.2 to do what I want, I should change to 2.18.0.  Considering
that http://www.lilypond.org/unix.html positively encourages us to use
the default version with distros such as Ubuntu (v2.14.2 in this case),
this is not what a new user might expect!

I did actually upgrade to 2.16.0 some weeks back, but I removed it and
reinstalled 2.14.2 via the Ubuntu package manager.  Until a few hours
ago, I couldn't remember why I reverted to 2.14.2, but I was sure I must
have had a good reason.

Anyway, I have now installed 2.18.0, and have now discovered again what
the problem with 2.16.0 was: Emacs can't find Lilypond mode any more.

I've just spent ages downloading the Lilypond source files, and trying
to understand what I am supposed to do with the files in
lilypond-2.18.0/elisp/

I have read
http://www.lilypond.org/doc/v2.18/Documentation/usage/text-editor-support
as well as the comments at the top of
lilypond-2.18.0/elisp/lilypond-init.el, but I'm still confused as to
what I need to do to get Emacs Lilypond mode working again.

Can someone help me sort this out, please, or will I have to go back to
using Lilypond 2.14.2 with no help other than the manuals?

of course not ... I see Vaughans idea as a first draft ... and now he's
able to use it in a global variable.
At least the example, he provided, should work this way.
But for a more robust implementation, there need to be score-level
context-properties - perhaps an engraver. We'll see later ;)

Won't be able to distinguish being called another time from the same
output (\layout, \midi, \musicxml (this one's hypothetical yet),
\addQuote...) or the next one.

What about a closure?
%%
autopan =
#(define-music-function (parser location)()
   (let ((mypan (+ autopan-current-voice 1.0)))
(set! autopan-current-voice mypan)
(make-music
 'ApplyContext
 'procedure

   (+ -1.0
 (* mypan
   (/ 2.0

 )
   )
 )))
   ))
 ))
%%

At least now every Staff gets its own midiPanPosition.

I like the idea of auto-stereo-spreading midi channels. Now it should
also work, if autopan is used inside a global variable.
Still, I'd recommend usage of either a global context property or a
performer/engraver that keeps track of all contexts using autopan.
Perhaps it is possible to count all contexts joining autopan automatically.

But thats out of scope for me right now ;) (i might come back later on
this topic)

Best, Jan-Peter

Doesn't work.  At the time the function gets called, _all_ instances of
the function get to see the same value of autopan-current-voice.

If you want to keep tabs on your current voice, you need to use a
score-level context property.

Both of them are not very informative. :)

Can you please do what follows?
Open the Terminal and enter
/opt/local/bin/frescobaldi
Frescobaldi should start and (probably) give the same error, but this
time there will be some (hopefully more meaningful) messages in the
Terminal.
Close Frescobaldi and copy&paste here the full Terminal transcript
(starting from the line you entered).

Re: Auto-panner

Thanks, David.
@Vaughan
For a short test ... this compiles, but I can't listen to the resulting
pan in midi 
I changed the PropertySet to ApplyContext with a lambda. This should
work in variables, as it returns an applyContext expression.
As with the previous solution, you have to care about the order autopan
is called.
It might be a good idea to either use a performer (engraver in midi
context) and/or to track context id's, so that each context is counted once.

Re: Semi-transparent color in Lilypond

[Rupert Snook]

Thanks Patrick and Harm for the suggestions! These could work as
workarounds, but still not exactly what I'm after. I'm looking for a color
that has an opacity / transparency channel, and this channel could be set
between 0% (fully transparent) and 100% (fully opaque).

If that's not possible, maybe a work around could be to import a pre made
graphic that was already semi-opaque.

Re: Auto-panner

Hi Vaughan,

if global is a music-function calling autopan, it will evaluate it
everytime. If global is a variable, its value is set, once it is assigned.
So if you have to wrap it in music-function. If you always have a
variable "global" containing all you need, you can wrap that in a function:


music = { c'' }

global = { \time 4/4 }
% another name than "global"!
meta =
#(define-music-function (parser location)()
   #{
 \autopan \global
   #})

\new Staff <<
\meta
\music
>>


"global" is only a function, if it is declared one. Otherwise it is just
a variable.

BTW, nice autopan utility ;)

Frescobaldi on Mac installation instructions moved to Frescobaldi's wiki

[Davide Liessi]

Dear Frescobaldi & Mac users,

the installation instructions for Frescobaldi on Mac OS X have been
moved to Frescobaldi's wiki
(https://github.com/wbsoft/frescobaldi/wiki).

They have also been updated, as a consequence of a recent
reorganization of the Portfile for Poppler, so it is no longer
necessary to install Poppler separately before Frescobaldi.

You can find them at

Looking at midi files created with NoteWorthy Composer, e.g.:

it should be possible to create a good readable .ly files.
Dumping this midi file with midi.pl, it easy to identify

That one looks just like a bad file name.  Sure the file is not named

Since you're focussing on Perl tools: the CPAN module MIDI::Tweaks comes

Auto-panner

[Vaughan McAlley]

I was so excited by \set Score.midiPanPosition that I was inspired to
write a function in Scheme that spreads the voices evenly from left to
right. It can’t look ahead to find the number of voices or staves,
that needs to be specified at the start or before a new \score
definition:

\version "2.18.0"

\include "autopan.ly"
\SetTotalAutopanStaves #4

myMusic = \relative c' {
   \time 4/4
   c4 d e f g1
}

\score {
   <<
  \new Staff {
 \autopan
 \transpose c bes \myMusic
  }
  \new Staff {
 \autopan
 \transpose c g \myMusic
  }
  \new Staff {
 \autopan
 \transpose c e \myMusic
  }
  \new Staff {
 \autopan
 \transpose c c \myMusic
  }
   >>
   \layout {}
   \midi {}
}

%%

Because I’m lazy, I’d love to include the \autopan command in \global,
but it looks like when \global is evaluated, the function is evaluated
and its return value is permanently made part of \global, which means
everything is panned to the far left. Is there a way to make the
function run every time \global appears?

On Windows 7 32-bit it works fine as long as you call python-windows.exe 
instead of python. E.g.


python-windows lilymidi.py --pretty somefile.mid

On my LilyPond 2.18.0 on OSX (Intel) 10.9 there’s a wrong MIDI library in 
LilyPond:

$ lilymidi --pretty something.mid
Traceback (most recent call last):
  File "/Applications/music/LilyPond.app/Contents/Resources/bin/lilymidi", line 
250, in 
go ()
  File "/Applications/music/LilyPond.app/Contents/Resources/bin/lilymidi", line 
231, in go
midi_data = read_midi (midi_file)
  File "/Applications/music/LilyPond.app/Contents/Resources/bin/lilymidi", line 
67, in read_midi
import midi
ImportError: 
dlopen(/Applications/music/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so,
 2): no suitable image found.  Did find:

/Applications/music/LilyPond.app/Contents/Resources/lib/lilypond/current/python/midi.so:
 mach-o, but wrong architecture

Transparency is not possible in PostScript, but just in PDF - you can „inject“ 
it with pdfmarks, though. Maybe it would be possible to load a definition with 
a handwritten EPS.

Frankly, I think we might want to sort that under "stupid LilyPond"
instead as that means we only have one stupidity to cure.

This has had me annoyed rather often as well, and it does not make a
whole lot of sense either since any output definition but \layout seems
pointless in a score markup.

Might want to mark this as an enhancement request.

Uh, this is awkward, but you do know that the LilyPond distribution
comes with a program called lilymidi which you can use like

lilymidi --pretty somefile.midi

in order to get a readable representation of a Midi file?

  I'm experimenting with midi file to lilypond conversion since
midi2ly creates files that are hard to read for me, and thus makeing
it hard to use its output. Yes I can write a program to tidy up its
output, and I did so, but looking at the dump of a midi file with
this simple program:

/// midi.pl:
#!/usr/bin/perl -w

use strict;
use MIDI;

sub proc_file($);
my $file;
foreach $file (@ARGV) {
 proc_file($file);
}


sub proc_file($) {
 my $file = shift;

 my $opus = MIDI::Opus->new({ 'from_file' => $file });
 $opus->dump({ "dump_tracks" => 1 });
}
///

I started to experimenting extracting e.g. header data etc. in
the program:

  http://turkos.aspodata.se/git/musik/bin/miditoly.pl

(Which is work in progress.)

Looking at midi files created with NoteWorthy Composer, e.g.:

  http://www.cipoo.net/downloads/midi/LottiAminAgnus.mid

it should be possible to create a good readable .ly files.
Dumping this midi file with midi.pl, it easy to identify
what goes where.

If you can create example files (midi and pdf) created from
notesetting programs, perhaps we can identify heuristics for a
nice conversion to ly-code.

Idéas and suggested conventions for the generated code are also
welcome.

Hi,

Perhaps you don't know midicomp.
Here the latest version:
https://github.com/markc/midicomp

It gives you all information on a midifile.
As you know Perl there is a tiny exemple to use it with midicomp in the 
README.

Perhaps it's worth to try a nice conversion to ly-code.
HTH.
Phil.

I think so and I've created
